摘要
包头市土壤肥料工作站通过对玉米施用硅肥的肥效试验,验证硅肥的增产作用,结果表明,在同一试验条件下施35-50kg/667m^2硅肥作基肥,其增产率为6.7%～19.1%;施入40kg/667m^2作追肥,其增产率为17.4%～21.4%。从而为硅肥在玉米上的推广应用提供了科学依据。
Silicon fertilizer was first research and Korea , Thailand , Philippine , Taiwan region , extensively used in Japan. Following Japan, S. most Europe agricuhural developed countries and U.S.A. ,etc. also carried out plenty of researches for silicon and use silicon by a large scale, silicon fertilizer have brought high benefit for their agriculture, the silicon research and applicatiox： in our country start late comparatively, and concentration in the south areas of Changjiang with nortlxeast and the North China region is blank basically.Silicon fertilizer efficiency test on maize had been down in Baotou city soil fertilizer work station , the fertilizer efficiency of silicon verified, resuh indicate that application of Silicon fertilizer35-50kg as base fertilizer can increase yiehl 6.7% 19.1% and top application 40kg per mu can increase yield 17.4%-21.4%. Thus result offer scientific basis for silicon fertilizer application on the maize
